A boy pressured me into sex and now I’m pregnant and my mom doesn’t believe me :/

Can anyone please give me some advice? I’m freaking out. I was staying over my aunts house and she had a bunch of people over. Her friends have a son who is about my age. We were in the living room and he convinced me to go to the bedroom and he forced himself onto me. I didn’t tell anyone and ended up locking myself in my aunts room until everyone left. I didn’t say anything to anyone but this week I’ve been really sick and I didn’t even think of it but then I started getting paranoid and I broke down and told my mom and she made me take a pregnancy test and it was positive. She doesn’t believe that he forced himself on me and she thinks I have been having sex and I haven’t. I don’t know what to do and I don’t want to have a baby. Please anyone tell me what I can do to fix this. My life was so normal and now it’s a nightmare.
